Can you bring formula on a plane? The positive aspect is that you are able to do exactly this. If you understand the airline’s rules, prepare ahead and gather the proper supplies, your trip may go much more smoothly and comfortably. If you’re using either type of formula, we can help you keep your baby relaxed, healthy and comfortable on your journey.

Can You Bring Formula on a Plane?
You are allowed to travel with a formula on an airplane. Parents and caregivers can go through airport security and bring baby formula on flights, both the TSA and most airports allow it. Since formula is a medically important liquid, it is not included in the limit of 3.4 ounces that applies to all other carry-on items.
TSA allows you to pack:
- Liquid food that is supplied in an easy-to-use container.
- Water that is used for mixing the formula.
- Freezer packs come in handy for keeping breast milk or formula chilled.
- Formula can be added to your carry-on baggage in an amount required for a single flight, regardless of the liquid limits. Though TSA agents may want you to take the formula and its supplies out for a separate check, you do not need to test or open the containers or bottles. Agents can inspect the container’s outside and vapor using different non-destructive methods.
Let the TSA officers know as soon as you begin screening that you have baby formula. This will make things easier and help avoid any misunderstanding. You could also state that the inspection should be done while wearing gloves and in a tidy setting.
Can You Bring Powdered Formula on a Plane?
It is permitted to pack powdered formula in your bags, and most people find it easiest to travel with babies using this type of formula. Powdered formula is not covered by the same screening rules used for liquids. Still, there are some points you should remember:
- If the formula powder in your bag is greater than 12 ounces (350 mL), TSA may need you to take it out for individual screening. Doing this is a normal practice when a substantial amount of powder is in use.
- Screening: You could be instructed to place the container in a separate spot to be X-rayed. If the agent cannot identify the substance visually, they may swab or test the contents. Occasionally, you won't need to open the container, and if you have concerns about bacteria, you can request that the formula not be opened.
- Try to store the powdered formula in the container it came in. You can also measure your portions ahead of time and keep them in separate containers. Ensure your formula bottles are easily recognizable, and it would be helpful to bring a printout of the TSA rules about baby formula in case you meet someone who does not know the rules.
- For Mixing Water: When mixing formula on the airplane, you are permitted to have bottled water only for this use. Make sure the TSA agent is aware that you need to bring baby formula; they will treat it to the appropriate standards.
How to Take Baby Formula Through Airport Security
Bringing baby formula through airport security might seem stressful for novice parents, but that’s because it is allowed and usually not a problem. Here are the best ways to streamline the process:
- Don’t Hide It
When you’re close to security, indicate to a TSA official that you’re carrying baby formula. This process helps stop delays and guarantees your shipment is correctly inspected.
Your two extra hands at the checkpoint: Slip into a Momcozy Baby Carrier so you can breeze through ID checks and bag bins while baby stays settled against you. Perfect for long lines and tight connections.
- Always remove substances such as formulas and supplies from the area when you are done working.
Make sure to take away every formula container, bottle and jug of water from your bag. Move these products to a different place for review. Don’t forget to take out any ice or gel packs you have in the freezer.
- Be Prepared for Additional Checks When Buying Lots
If your formula weighs over 12 ounces, it will likely be inspected further. TSA may scan the outside of the containers or use non-contact methods for detection, but they are not allowed to ask you to taste the formula or open sealed containers.
- Resources for Getting Help
If something makes you feel uneasy, let a supervisor know or get the items checked where they’re clean and apart from the rest. You are allowed to take baby formula through security, as long as you are not carrying too much.

How to Travel with a Formula on a Plane
With some preparation, traveling with a formula won’t be difficult. It’s important to plan how you will keep, prepare and give formula to your baby on a trip. Below are some suggestions endorsed by parents:
- Measure Your Food in Portions Before You Eat.
Sort out the same amount of powdered formula for each serving ahead of time to shave off preparation time when you’re on the plane. Don’t struggle with the scoops and snack bags in your tight airplane space.
- Bring a Water Warmer You Can Trust
If you like to give your formula at the right temperature, a portable water warmer is really helpful. The Momcozy Superfast Portable Breast Milk & Water Warmer is especially made for mothers who need to warm the milk fast. You can use the hot water to quickly heat baby formula—you'll never have to worry about cold flight water again.
- Carry a Portable Cooler
Use a compact cooler to ensure your baby’s liquid formula is both fresh and safe. If you need to take breast milk on a trip, the Momcozy Portable Breast Milk Cooler for Outdoor (22oz) is your best choice. Because it is lightweight and simple, it is ideal for keeping drinks cold when others surround you at the airport for long periods.
- You can pick between powdered and ready-to-feed formula. Compared to regular formula, powdered formula is easy to carry, does not take up liquid space, yet you’ll need water and a way to warm it.
- Ready-to-feed formula is handy, although the containers are much bigger than for powdered types. Keep your bottle of liquid in a cooler and tell officials that it's needed for infant feeding.
How Many Bottles Should I Pack?
As a rule, carry one bottle for every 2–3 hours of your journey and be sure to have one or two extras in case something happens. For example:
- Flying for 6 hours plus an extra 2 hours at the airport usually means you’ll need at least 3–4 bottles. Park a lightweight Momcozy Stroller as a stable prep base for bottles during layovers. Your little one relaxes with a snack or catnap while you reorganize bags; quick-fold design is gate-check friendly.
- Remember to put a spare charger in your bag when you are taking an international flight or will be waiting for hours at an airport.
- Wash and sterilize the bottles before putting them in a clean bag or cooler. It’s best to keep anti-colic bottles with many parts inside, as they can get disassembled and create confusion.
How Much Formula Should I Pack?
Always take a bit more formula than you imagine you’ll require during your trip. Trying this estimate for packing helps:
(Formula consumed daily) × 1.5 = how much you need for the whole trip
If your baby takes in 24 oz/day, prepare 36 oz/day to have on hand for when you travel.
For a formula in powder form, portion the needed number of feedings, including some additional servings. Don't hesitate to travel with a canister in your carry-on and leave larger bottles with the other baggage.
How to Keep Baby Formula and Food Safe on a Plane
Temperature is very important, so be sure to follow instructions for pre-mixed or ready-to-feed formulas. You can do this by following these instructions:
- Carry a Travel Cooler with you.
You may use ice packs or frozen gel packs for your baby’s food or formula, as TSA has approved them.
- Don’t Add Color Too Soon
Only add water to your powdered formula when you want to feed your baby. It lowers the chance of bacteria developing. If you mix your formula in advance, put it in a cooler and serve it within 1 or 2 hours.
- Be Careful with Cleaning and Sanitizing
Place a few sterilized filled bottles in zip-top bags and carry extra ones in your bag in case the first ones get dirty or damaged. You can easily clean your bottle with travel bottle wipes or a little bottle brush with travel dish soap.
- Never Use Water from Toothpaste
If you use baby formula, be sure to use purified or nursery water for mixing it. Some airlines will offer hot water for meals, but it’s always best to find out if it’s too hot for babies.
Conclusion
Proper preparation and the proper equipment will help ensure your baby's comfort and a full belly from when you check in till you arrive at your destination. Expect delays at security, bring extra items just in case and use smart. Can you bring formula on a plane? Of course, you'll be safe, confident and at ease. Simply use the instructions, stay neat and don't hesitate to get help if necessary. Don't worry, you're doing great, and your baby will be grateful.
